Compliance & Data Protection

Privacy Policy

Last Updated: September 18, 2026 • Effective Year: 2026

1. Overview and Our Commitment

CALCONOVA (“Portal”, “We”, or “Platform”) places the utmost priority on protecting user privacy and personal data. This Privacy Policy is crafted in full compliance with global data protection frameworks, including the EU General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA/CPRA), and related data protection standards.

Our calculation tools are architected to execute entirely client-side in your browser. Personal financial, biometric, or tax inputs entered into calculation forms are never stored on our servers and are never tied to individual user profiles.

2. Information We Collect and How It Is Used

Calculation Inputs: Processed exclusively in your browser memory. Only encoded into query parameters when you explicitly use our URL State Sharing feature; never written to a server database.
Calculation History & Favorites: Saved calculations and bookmarked tools reside strictly in your browser's LocalStorage and are completely inaccessible to our servers.
Community Studio (calconova.net) & Feedback Submissions: When publishing a community tool, only your public author handle, tool title, documentation, and AST formula schema are made public. Optional feedback and DMCA email addresses are used solely to resolve your specific inquiry.
Technical Traffic Logs: Pursuant to infrastructure security standards, HTTP request logs (IP address, timestamp, HTTP status, requested URL) are retained on Cloudflare for up to 2 years with cryptographic hash integrity. Calculation form inputs are never logged.

3. Data Retention Matrix

We adhere strictly to “Privacy by Design” and “Data Minimization” principles. Data retention durations across categories are detailed below:

Data Category	Storage Location	Retention Period	Statutory Basis / Purpose
Financial / Health Calculation Inputs	Not Stored on Servers (Client RAM Only)	0 Seconds (Instantaneous)	Purged from memory immediately upon simulation termination.
Calculation History & Favorites	User Browser (LocalStorage)	Until browser cache is cleared	Enables offline tool recall strictly on your local device.
Cookie Consent Preferences	User Browser (LocalStorage)	1 Year or until reconfigured	Demonstrable consent compliance under GDPR Article 7(1).
Server Access & Security Logs	Secure Cloud Infrastructure (Cloudflare)	2 Years	Cyber defense, DDoS mitigation, and statutory compliance.
Contact Inquiries & DMCA Claims	Encrypted Corporate Mail Archive	3 Years (Statute of limitations)	Resolution of consumer, copyright, and formal legal claims.

4. Cookies, Strict Opt-In, and Consent Management

CALCONOVA uses browser cookies and LocalStorage across calconova.com and calconova.net to preserve theme preferences, currency choices, and facilitate compliant advertising delivery.

Strictly Necessary & Functional Cookies:

Required for theme mode (dark/light), locale routing, CSRF protection, and consent storage. Do not require prior opt-in.

Analytics & Advertising Cookies:

Employed by Google AdSense (DART / DoubleClick) to anonymously measure page performance and serve relevant ads. Activated ONLY upon explicit user consent via “Accept All” (Strict Opt-In).

Equal-Weight Choice & Privacy by Default: We strictly prohibit dark patterns: the “Reject All” and “Accept All” buttons share equal visual styling, color, and size. You can adjust your consent at any time via the “Cookie Preferences” link in the footer.

5. Google AdSense, DART Cookies, and DoubleClick Usage

To maintain free and accessible calculation tools worldwide, we partner with reputable third-party advertising networks, primarily Google AdSense:

Google DART Cookie: Google, as a third-party vendor, uses DART cookies and DoubleClick technology to serve advertisements on our portal.
Interest-Based Advertising: DART cookies allow Google and its partners to serve ads based on prior visits to our site and other destinations across the web. Ads remain non-personalized (data-npa="1") unless explicit consent is provided.
Opt-Out Mechanisms: Users may opt out of personalized DART advertising by visiting Google Ads Settings (adssettings.google.com) or using the aboutads.info choices tool.

6. User Rights (GDPR, CCPA/CPRA, and DSR Requests)

Under GDPR (Articles 15–22), CCPA/CPRA, and applicable privacy laws, all visitors have enforceable rights:
